A 76-year-old man with chronic obstructive pulmonary disease (COPD) presents complaining of 3 weeks of cough and progressive dyspnea on exertion in the setting of a 20 pound weight loss. He is a 60 pack-year smoker, worked as a shipbuilder 30 years ago, and recently traveled to Ohio to visit family. Chest radiograph shows increased bronchovascular markings, reticular parenchymal opacities, and multiple pleural plaques. Labs are unremarkable except for a slight anemia. Which of the following is the most likely finding on this patient's chest CT? A. Nodular mass spreading along pleural surfaces B. Honeycombing C. Air bronchogram D. Granulomatous nodule E. Lower lobe cavitary mass

A 43-year-old woman presents to her primary care physician with complaints of mild shortness of breath and right-sided chest pain for three days. She reports that lately she has had a nagging nonproductive cough and low-grade fevers. On examination, her vital signs are: temperature 99.1 deg F (37.3 deg C), blood pressure is 115/70 mmHg, pulse is 91/min, respirations are 17/min, and oxygen saturation 97% on room air. She is well-appearing, with normal work of breathing, and no leg swelling. She is otherwise healthy, with no prior medical or surgical history, currently taking no medications. You have a low suspicion for the most concerning diagnosis and would like to exclude it with a very sensitive though non-specific test. Which of the following should you order? A. Obtain spiral CT chest with IV contrast B. Obtain ventilation-perfusion scan C. Obtain chest radiograph D. Order a lower extremity ultrasound E. Order a D-dimer
E. Order a D-dimer
A patient who appears very anxious enters the office complaining of dizziness with perioral and extremity paresthesias. She vaguely describes some chest discomfort. Physical examination is unremarkable, except for moderate tachypnea with obvious sighing respiration. This clinical picture is most consistent with A. bronchial asthma. B. hyperventilation syndrome. C. spontaneous pneumothorax. D. emphysema.
